Can you work out what the river is trying to do by using this diagram?
Gradient = Rise(need to reduce)
Run (need to increase)
Headward Erosion – lengthens course
Vertical Erosion downcutting reduces gradient
Lateral Erosion – meandering lengthens course
(in the delta) lengthens course
(on the bed) Reduces gradient
